What makes this slug so ninja-like? Because these slimy fellers shoot chalky "love darts" at potential mates which pierce and inject the proper hormones to make them hot and horny. Hmm..maybe it should be called the Roofie Slug, instead?

The "ninja" slug is a newly (in 2010) discovered, long tailed slug found in the mountains in Malaysia. The skeet-like mechanism these slugs use isn't 100% effective but just "increases the chances of reproduction". Whatever works, I guess.

Also unique! They wrap their tail (which is 3 times the length of its head) around its body when it's inactive. Check out the weirdest new animals of 2010 at National Geographic. [National Geographic]
